I recall some president of an African country being asked how can America help.
“Stop sending us your used clothing!! We are training people to make clothing, and providing them with cheap loans to start factories. So they can earn money and buy clothing made here. But the don’t buy it (or make it) when they can get it for free! Stop it!!”
I heard a similar complaint about food aid. The food for the “starving” people usually arrives about two weeks before the year’s harvest starts, so the farmers have to compete with shiploads of free food.
